与VERT设备不同的是,MyJump2设备准确可靠地测量了沙子上的垂直跳跃高度. 这一发现对于评估排球和足球等沙运动中的运动员至关重要.
科学领域:
- 生物力学和体育科学 生物力学和体育科学
- 运动员表现测量测量方法
- 人类运动分析 人类运动分析
背景情况:
- 海运动需要在不稳定的沙面上进行爆炸式跳跃行动.
- 缺乏准确和可行的现场测量工具,用于沙子上的跳跃性能.
- 评估反运动跳跃 (CMJ) 的表现对于沙运动员的训练和人才识别至关重要.
研究的目的:
- 为了确定MyJump2和VERT设备在沙子上测量CMJ高度的可靠性和并发有效性.
- 为了将MyJump2和VERT的准确性与标准标准力板进行比较.
- 为在海运动场所提供有效和可靠的跳跃测量工具提供建议.
主要方法:
- 21名参与者在沙子表面上进行了5次CMJ.
- 跳跃高度同时使用力盘,MyJump2和VERT (惯性测量单位) 记录.
- 评估了可靠性 (类内相关系数 - ICCs,日间,间隔,内部) 和并发有效性 (ICCs,布兰德-阿尔特曼地块).
主要成果:
- MyJump2展示了近乎完美的内部 (ICC=0.98) 和内部 (ICC=0.98) 的可靠性.
- MyJump2显示了与力板相对近乎完美的并发有效性 (ICC=0.92,偏差=-2.31厘米).
- 尽管日常可靠性很好 (ICC=0.79),但VERT与力板的一致性仅为中度 (ICC=0.55,偏差=6.31厘米).
结论:
- MyJump2是一个有效和可靠的工具,用于评估在沙面上垂直跳跃的性能.
- 由于同时有效性不足,不建议使用VERT设备测量沙子上的跳跃高度.
- MyJump2为教练和研究人员提供了一个实用的解决方案,用于评估海运动中的运动员.
